Angiography conducted in 29 anginal patients has shown that coronary arteries were intact in 23 and little affected in 6 of them. Signs of myocardial ischemia were recorded at myocardial scintigraphy, bicycle ergometry, 24-h ECG monitoring in 17 patients. Esophageal lesions confirmed by endoscopy, manometry, esophageal pH-metry with Bernstein test were revealed in 20 examinees (68%). It is suggested that patients with persistent chest pain and unaffected coronary arteries who are resistant to antianginal therapy should undergo functional study of the esophagus including endoscopy, manometry and pH-metry.
对29例心绞痛患者进行的血管造影显示，其中23例冠状动脉完好无损，6例受影响较小。17例患者在心肌闪烁扫描、自行车测力计测试、24小时心电图监测中记录到心肌缺血迹象。20名受检者（68%）经内镜检查、测压、食管pH值测定及伯恩施坦试验证实存在食管病变。建议对持续胸痛且冠状动脉未受影响但对抗心绞痛治疗无效的患者进行包括内镜检查、测压和pH值测定在内的食管功能研究。
